Abstract: A field experiment was conducted in kharif-2019 at Agronomy Farm, Rajarshee Chhatrapati Shahu Maharaj College of Agriculture, Kolhapur. An experiment was laid out in randomized block design with three replications and seven treatments comprising five levels of zeolite (60, 80, 100, 120 and 140 kg ha-1). The total uptake of N, P, K and micronutrients (Fe, Mn, Zn and Cu) in paddy increased significantly due to zeolite application. Significantly the highest N (66.97 kg ha-1), P (20.17 kg ha-1), K (67.57 kg ha-1) and micronutrients viz. Fe (1790 g ha-1), Mn (990 g ha-1), Zn (155 g ha-1) and Cu (120 g ha-1) were recorded in treatment T7 (GRDF + Zeolite @ 140 kg ha-1) and these were at par with the treatment T5 (GRDF + Zeolite @ 100 kg ha-1) and T6 (GRDF + Zeolite @ 120 kg ha-1). The application of different levels of zeolite along with GRDF increased the N, P and K use efficiency of paddy. The highest nitrogen use efficiency (51.66 %), phosphorus use efficiency (53.80 %) and potassium use efficiency (96.25 %) recorded in the treatment T7 (GRDF + Zeolite @ 140 kg ha-1), but these values were at par with the values recorded in treatment T5 (GRDF + Zeolite @ 100 kg ha-1) and T6 (GRDF + Zeolite @ 120 kg ha-1). The results of the present investigation indicated that the application of zeolite @ 100 kg ha-1 along with GRDF was found effective in increasing nutrient uptake of paddy and nutrient use efficiency in soil.
